Hello, I purchased a 10 inch monitor and back up camera wire connections, I ran the wire under the chassi frame mounted the camera on top of the existing back up camera used for keeping an eye on the tow vehicle. I drop the wire through the back shell on my class A, ran the wire through the chassi frame and into the instrument panel drivers side, mounted my monitor above the drivers side sun shade cabinet and pick up 12 volts power from the accessories switch on the instrument panel. I use it to monitor behind the coach get better view past the tow vehicle, thus providing me with viewing clearance when passing and switching lanes. Little trouble to install but well worth it.
